Notes:
• Several rows with the same NPI-TON or Phone-Context are allowed.
In such a scenario, a Tel-to-IP call uses the first match.
• Phone-Context '+' is a unique case as it doesn't appear in the
Request-URI as a Phone-Context parameter. Instead, it's added as a
prefix to the phone number. The '+' isn't removed from the phone
number in the IP-to-Tel direction.
